7E WILL ILLUSTRATE TWO EXAMPLE ORGANIZATIONS THAT WERE USED ON
THE 'LOBAL 3TUDIO 0ROJECT '30 $URING THE FIRST TWO YEARS OF THE
'30 A PRODUCT STRUCTURE APPROACH WAS USED TO ORGANIZE THE PROJECT
AND AN EXTENDED WORKBENCH MODEL DEVELOPMENT PROCESS WAS USED
;3ANGWAN ET AL = 4HIS RESULTED IN A HUB AND SPOKE ORGANIZATIONAL
STRUCTURE &IGURE WHERE THE REMOTE COMPONENT DEVELOPMENT
TEAMS COMMUNICATED MOSTLY WITH THE CENTRAL TEAM ROLES E G CHIEF
REQUIREMENTS ENGINEER CHIEF ARCHITECT PROJECT MANAGER AT THE
HEADQUARTERS OR CENTRAL SITE
2EQUIREMENTS INFORMATION IS TRANSFERRED FROM THE CENTRAL TEAM TO
EACH REMOTE COMPONENT DEVELOPMENT TEAM IN THE FORM OF MODELS
AND SPECIFICATIONS 4HE DOCUMENTATION PACKAGE IS USED TO HELP
COMMUNICATE TO THE REMOTE TEAMS THE WORK THAT WILL BE DONE IN
ACCORDANCE WITH THE DEVELOPMENT PLAN 4HE WORK TO BE DONE IS
SCOPED TO BE IMPLEMENTED BY A RELATIVELY SMALL COMPONENT
DEVELOPMENT TEAM MAXIMUM OF TEN ENGINEERS 4HE ROLES OF THE
DEVELOPMENT TEAM MEMBERS ARE MULTIFUNCTIONAL INCLUDING DOMAIN
DESIGN DEVELOPMENT AND TESTING EXPERTISE 4HUS WITH THE EXTENDED
WORKBENCH MODEL REQUIREMENTS DEFINITION AND ANALYSIS ARE DONE BY
THE CENTRAL TEAM AT A SINGLE SITE HOWEVER DOMAIN EXPERTISE IS
DEVELOPED OVER TIME AT THE REMOTE SITES /NE WAY TO BUILD UP THIS
REMOTE DOMAIN EXPERTISE IS TO HAVE THE REQUIREMENTS ENGINEERS AT THE
REMOTE SITES WORK AS TEMPORARY MEMBERS OF THE CENTRAL SITE S 2% TEAM
AND THEN SERVE AS THE DOMAIN EXPERTS IN THE REMOTE TEAM
4HIS HUB AND SPOKE ORGANIZATION IS TYPICALLY USED WHEN A CENTRAL
ORGANIZATION IS UTILIZING REMOTE DEVELOPMENT SITES FOR THE FIRST TIME )T
OFTEN WILL TAKE A YEAR OR MORE TO BE ABLE TO DEVELOP THE DOMAIN EXPERTISE
2% AND DEVELOPMENT SKILLS IN THE STAFF IN THE REMOTE TEAMS 4HUS THE
CENTRAL TEAM TRANSFERS SOME OF THEIR KNOW HOW TO THE REMOTE TEAMS OVER
TIME SUCH THAT THEY ARE ABLE TO TAKE ON A BIGGER ROLE IN THE DEVELOPMENT
PROJECT 7E RECOMMEND TO ORGANIZATIONS STARTING DISTRIBUTED
DEVELOPMENT FOR THE FIRST TIME TO TAKE A LONG TERM VIEW SINCE THERE WILL
BE A SUBSTANTIAL LEARNING CURVE TIME NECESSARY FOR THE REMOTE TEAMS TO
BECOME PRODUCTIVE CONTRIBUTORS TO THE DEVELOPMENT PROJECT
